Plain English
Optimism is an Ethereum optimistic rollup designed for EVM equivalence — meaning Ethereum contracts work without modification. It is the technology behind the Superchain, a cluster of L2s including Base, Worldchain, and Mode that share security and tooling. OP is the governance token.
How it actually works
The OP Stack is open-source rollup software anyone can deploy. Coinbase’s Base is built on it. Optimism revenue from sequencer fees funds the Optimism Collective, which distributes retroactive public goods funding. Withdrawal time is 7 days unless routed through a third-party bridge.
What it means for you
Optimism’s strategy is being the shared infrastructure for L2s rather than competing for users directly. The OP token captures value as more chains join the Superchain and contribute fees back. For builders, deploying on OP Stack is the path of least resistance to launching a custom L2 with shared security.
